can build lenses out of meta-materials that can zoom to the micron level, making it possible to spot germs, chemical agents and even DNA
using basically a pair of binoculars. Similar lenses could focus even a tiny amount of ambient light and use it as a power source. Hammond calls that his "anti-cloak." This so-called "super-lens" is already in development by Purdue University and private partners. Hammond said an early version could be ready in two or three years
Soldiers could one day conduct covert operations in complete secrecy, now that Pentagon-backed physicists have figured out how to mask entire events by distorting light.
Masking an object entails bending light around that object. If the light doesn’t actually hit an object, then that object won’t be visible to the human eye. Where events are concerned, concealment relies on changing the speed of light. Light that’s emitted from actions, as they happen, is what allows us to see those actions happen. Usually, that light comes in a constant flow. What Cornell researchers did, in simple terms, is tweak that ongoing flow of light — just for a mere iota of time — so that an event could transpire without being observable.
The entire experiment occurred inside a fiber optics cable. Researchers passed a beam of green light down the cable, and had it move through a lens that split the light into two frequencies, one moving slowly and the other faster. As that was happening, they shot a red laser through the beams. Since the laser "shooting" occurred during a teeny, tiny time gap, it was imperceptible. It’d take a machine 18,600 miles long to produce a time mask that lasts a single second.
British defense company BAE Systems has developed an "invisibility cloak" that can effectively hide vehicles from view in the infra-red spectrum.
